The footer needs to be styled before we release.
In this patch, I have added a background colour to the footer, centred everything, and spaced the footer contents out. Please see the attached screenshots for the before shot and after shots.
It's not my favourite design, but it is a start for 11. (Better than no styling.)
I plan to come back a revise the footer later for 11.x, but I will submit that as a later design.
There is a small changed to the default.sakai.properties.
